Answer:
y= -1
Step-by-step explanation:
-4(y-2) = 12
-4y + 8 = 12
-4y = 12 - 8
-4y = 4
-4 -4
y= -1
To check:
-4 (-1-2) = 12
-4 (-3) =12
12 = 12
Answer:
y=-1
Step-by-step explanation:
-4(y-2)=12
-4y+8=12
-8=-8

Peter Piper's Pizza most popular pizza is the personal pan pizza. The personal pan pizza is 10 inches in diameter. What is the circumference of the pizza?
A. 3.14 inches
B. 10 inches
C. 31.4 inches
D. 314 inches
Answer:
C.) 31.4 inches
Step-by-step explanation:
The circumference of a circle is the linear distance of a circle's edge. Pretty much the perimeter of a circle.
Determine the radius of a circle, which is 5 inches (The radius is the diameter divided by 2)Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 5 = 31.4159The students in Ms. Douglas’ class worked so hard this year that she has planned a surprise, end-of -year trip for them to a local amusement park. The school principal allows Ms. Douglas to spend a budget of $500 on the trip.
So far she knows :
A coach bus costs $180 to transport them to and from the park.
Price of admission to the park is $15 per person
Part A : Write an inequality that describes that how many students Ms. Douglas can bring on the trip. Define the variable
Part B: Solve the inequality and explain the solution in the context o the problem
Answer:
Part A: 180+15x=500
B: x = 21.333 or 21
Step-by-step explanation:
So in part A since you have 500 to spend and 180 goes to the coach bus, you are left with $ 320 to spend on the students and when you divide 320 by 15, (since the tickets for admission are $15) you end up with 21.333, but since you cant bring .333 of a student on a trip you can bring 21 students, but you can buy 21.333 tickets.

The area of a 2D form is the amount of space within its perimeter. The total surface area of the square base pyramid is 297mm².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The total surface area of the square pyramid is the sum of the area of the triangles and the area of the base. Therefore, the total surface area is equal to,
Total surface area = Area of square base + 4(Area of a triangular face)
= (9mm)² + 4(0.5×9×12)mm²
= 81mm² + 216mm²
= 297mm²
Hence, the total surface area of the square base pyramid is 297mm².
